玉米‖大豆宽窄行间作种植模式研究

摘要

以湘春豆26和临奥1号为材料,设置了玉米 ‖ 大豆宽窄行间作(带状复合种植新模式)、玉米 ‖ 大豆等行距间作(农民习惯栽培)、玉米单作(农民习惯栽培)和大豆单作(农民习惯栽培)4种种植模式,研究不同种植模式下大豆和玉米农艺性状和经济效益的差异.结果表明:玉米 ‖ 大豆宽窄行间作模式的效益最高,达到1441.73元/667m2,分别比大豆单作、玉米单作增加37.51%和16.41%;同时,该间作模式的土地当量比最高,为1.23.这表明玉米 ‖ 大豆宽窄行间作是玉米和大豆的最佳间种模式.%The four-planting-pattern experiment with soybean variety Xiangchundou 26 and maize variety Lin-ao 1 as tested materials, including a new pattern of maize-soybean compound strip planting called wide-narrow row intercropping and three other farmer conventional cultivation modes, such as maize-soybean equidistant row intercropping, maize monoculture and soybean monoculture, was designed to determine the differences of maize-soybean agronomic characters and economic benefits under different planting patterns in this study. The results showed that the economic benefit of maize-soybean wide-narrow row intercropping was the highest, up to 21625.95 yuan/hm2(RMB), and the land equivalent ratio of this mode was the highest at 1.23. Therefore, the maize-soybean wide-narrow row intercropping was the optimal intercropping pattern for maize and soybean in the study.
